Milky Way Over Screw Auger Falls

I spent a couple hours photographing at Screw Auger Falls on Friday night, working towards getting this shot figured out. It was very very dark and I tried a few light painting techniques but I didn’t like the way it was looking, so ultimately I did a 20 minute exposure for the foreground at ISO 1600. The sky is ISO 3200 for 25 seconds. I needed a way to keep the lens from fogging over during the long exposure, so I wrapped a wool sock around the lens barrel with chemical hand warmers in the sock to keep the lens warm, using gaff tape (something I have from my days a filmmaker) wrapped on top of the sock to keep it on the lens.
